Abstract
La presente invención se refiere a un método para añadir un ingrediente de aleación a una corriente vertical de metal fundido que desciende de un recipiente superior hacia una recipiente inferior, en donde el método consiste de: dirigir la corriente descendente a través de un conducto colocado verticalmente hacia el recipiente inferior; formar un baño de metal fundido en el recipiente inferior; cerrar por lo menos la parte inferior del conducto y la corriente descendente dentro de una cubierta tubular colocada verticalmente que tiene paredes periféricas verticales separadas horizontalmente de la corriente descendente para definir un espacio anular no llenado cerrado entre la cubierta y la corriente descendente; transportar el ingrediente de aleación hacia la cubierta; y dirigir el ingrediente de aleación hacia el interior de la cubierta y hacia la corriente descendente; la mejora consiste de los pasos de: fundir el ingrediente de aleación en forma fundida; dirigir el ingrediente de aleación fundido hacia la cubierta sin emplear un gas portador; proporcionar dentro de la cubierta, durante por lo menos parte del paso de dirección mencionada en primer término, un gas que puede expandirse dentro de la cubierta; y controlar la formación del lobo o película solidificada en el interior de la superficie de la cubierta restringiendo la cantidad del gas expansible en la misma, a fin de reducir el efecto de enfriamiento resultante de esta expansión.
